ABSTRACT

The disclosed computer-implemented method may include (i) receiving, by a camera system that includes at least one camera, input from a user instructing the camera system to adjust a framing of the camera, (ii) directing, by the camera system, the camera to adjust the framing, (iii) determining a predicted modified camera frame that approximates an actual modified camera frame predicted to result from directing the camera to adjust the framing, (iv) displaying, before completely receiving visual data that results from the actual modified camera frame from the camera, the predicted modified camera frame to the user, (v) receiving the visual data including the actual modified camera frame from the camera after the camera adjusts the camera frame, and (vi) displaying the actual modified camera frame to the user. Various other methods, systems, and computer-readable media are also disclosed.

BACKGROUND

Videoconferencing is an important function of computing devices for many users. Home users may videoconference with distant friends or relatives, while users at work may videoconference with colleagues scattered in different offices around the globe. For some users, videoconferencing may entirely replace coming in to a physical office to work. For a videoconferencing system to provide a high-quality user experience, the videoconferencing system must be responsive to user input to adjust conference attributes such as volume, display, and camera frames.

In traditional videoconferencing systems, a user may be able to direct the videoconferencing system to adjust a remote camera so that the user can better view a person, group of people, or environment on the other end of the videoconference. However, in some traditional videoconferencing systems, connection latency and/or physical camera features may introduce a lag between when a user directs the videoconferencing system to adjust the camera position and when the user's display is updated to show the new camera framing/composition. This display lag may be frustrating to users who may over-correct or under-correct for the desired camera framing due to the lack of immediate visual feedback. The instant disclosure, therefore, identifies and addresses a need for systems and methods for updating camera displays.

SUMMARY

As will be described in greater detail below, the instant disclosure describes systems and methods for updating camera displays by displaying a predicted modified camera frame image before receiving data that results from the actual modified camera framing.

In one example, a computer-implemented method for updating camera displays may include (i) receiving, by a camera system that includes at least one camera, input from a user instructing the camera system to adjust framing of the camera, (ii) directing, by the camera system, the camera to adjust the camera framing in accordance with the input from the user, (iii) determining a predicted modified camera frame that approximates an actual modified camera frame predicted to result from directing the camera to adjust the camera framing in accordance with the input from the user, (iv) displaying, before completely receiving visual data that results from the actual modified camera framing from the camera, the predicted modified camera frame to the user, (v) receiving the visual data including the actual modified camera frame from the camera after the camera adjusts the camera framing in accordance with the input from the user, and (vi) displaying the actual modified camera framing to the user.

In one embodiment, receiving the input from the user may include receiving the input from the user via a computing device that displays visual data received from the camera to the user and directing the camera to adjust the camera framing includes sending, from the computing device, a message to an additional computing device that includes the camera and that is located remotely from the computing device. In some embodiments, the visual data may include video data. In one embodiment, the camera system may include a videoconferencing system.

In some examples, determining the predicted modified camera frame may include determining the predicted modified camera frame based at least in part on a physical characteristic of the camera. In one embodiment, the physical characteristic of the camera determines an adjustment rate of the camera. In some examples, determining the predicted modified camera frame based at least in part on the physical characteristic of the camera may include dynamically detecting the physical characteristic of the camera. Additionally or alternatively, determining the predicted modified camera frame based at least in part on the physical characteristic of the camera may include identifying the physical characteristic of the camera based at least in part on previously received information about the camera. In some examples, determining the predicted modified camera frame may include determining the predicted modified camera frame based at least in part on a latency of a connection between the computing device and the additional computing device.

In some examples, displaying the predicted modified camera frame to the user may include displaying visual data received from the camera that is within a field of view of the camera but that is not within a previous camera frame displayed to the user. Additionally or alternatively, displaying the predicted modified camera frame to the user may include generating visual data based at least in part on visual data received from the camera and displaying the generated visual data within an area of the predicted modified camera frame that is outside a field of view of the camera and does not include data received from the camera.

In one embodiment, a system for implementing the above-described method may include several modules stored in memory, including (i) an input receiving module that receives, by a camera system that includes at least one camera, input from a user instructing the camera system to adjust framing of the camera, (ii) a direction module that directs, by the camera system, the camera to adjust its framing in accordance with the input from the user, (iii) a determination module that determines a predicted modified camera frame that approximates an actual modified camera frame predicted to result from directing the camera to adjust its framing in accordance with the input from the user, (iv) a display module that displays, before completely receiving visual data that results from the actual modified framing of the camera, the predicted modified camera frame to the user, (v) a data receiving module that receives the visual data including the actual modified camera frame from the camera after the camera adjusts its framing in accordance with the input from the user, (vi) the display module displays the actual modified camera frame to the user, and (vii) at least one physical processor that executes the input receiving module, the direction module, the determination module, the display module, and the data receiving module.

In some examples, the above-described method may be encoded as computer-readable instructions on a computer-readable medium. For example, a computer-readable medium may include one or more computer-executable instructions that, when executed by at least one processor of a computing device, may cause the computing device to (i) receive, by a camera system that includes at least one camera, input from a user instructing the camera system to adjust framing of the camera, (ii) direct, by the camera system, the camera to adjust the camera framing in accordance with the input from the user, (iii) determine a predicted modified camera frame that approximates an actual modified camera frame predicted to result from directing the camera to adjust the camera framing in accordance with the input from the user, (iv) display, before completely receiving visual data that results from the actual modified camera framing from the camera, the predicted modified camera frame to the user, (v) receive the visual data including the actual modified camera frame from the camera after the camera adjusts the camera framing in accordance with the input from the user, and (vi) display the actual modified camera frame to the user.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

The present disclosure is generally directed to systems and methods for updating camera displays. As will be explained in greater detail below, by predictively updating a visual display in response to user input without waiting for actual updated visual data, the systems and methods described herein may enable users to direct the camera system more accurately and efficiently by enabling users to immediately see the results of adjustments without intervening lag. In addition, the systems and methods described herein may improve the functioning of a computing device by improving the responsiveness of the computing device to user instructions. These systems and methods may also improve the fields of videoconferencing and/or video streaming by increasing the efficiency and accuracy with which a user is able to adjust a camera during videoconferencing and/or video streaming.

The following will provide, with reference to FIG. 1, a block diagram of example sources of latency in updating camera displays. Detailed descriptions of an example method for updating camera displays will be provided with reference to FIG. 2. In addition, detailed descriptions of example physical and virtual cameras will be provided in connection with FIGS. 3 and 4, respectively. Detailed descriptions of example camera frames will be provided in connection with FIGS. 5-9. Additionally, detailed descriptions of an example system for updating camera displays will be provided in connection with FIG. 10. Detailed descriptions of an exemplary graph of a camera display responding to user input will be provided in connection with FIG. 11

FIG. 1 is a block diagram of example sources of latency that may slow down the process of updating visual data in response to a user's input. In some examples, a user may view images and/or video on a screen 102 that are captured by a camera 114. The user may enter input into input controls 104 in order to adjust the camera framing, for example by panning, tilting, and/or zooming the camera. In some examples, network latency 108 may add a delay in between when the user enters the input and when camera 114 receives the input. Additionally or alternatively, encoding and/or decoding the message sent from input controls 104 to camera 114 may cause latency. Once the message reaches camera 114, camera control 112 may introduce additional lag as camera 114 may not actuate instantly upon receiving input and/or may take some time to accelerate the camera due to the physical inertia of the camera mass. In some examples, camera control 112 may drive a motor to physically move and/or zoom a lens of camera 114. Additionally or alternatively, camera control 112 may process the image inside the camera in concert with lens, sensor, and/or image processing 113. After camera 114 has adjusted as requested by the user, further delay may be introduced before the user can view the updated camera frame on screen 102. For example, encoding latency may add latency as the image and/or video data is encoded and/or compressed, network latency may affect the return trip of the data through network interface 108, and/or decoding latency may add latency as the image and/or video data is decoded and/or decompressed after being received from network interface 106. Finally, the user may see the updated camera frame on screen 102. Due to the numerous sources of latency, some users may over-correct or under-correct when making adjustments to a camera frame. In some examples, a user may press a key to pan, zoom, and/or tilt a camera, wait for the updated camera frame to be displayed, and then repeat their action, slowly nudging the camera in the desired direction. By showing a predicted modified camera frame to a user immediately after a user directs the camera system to adjust the camera framing, the systems and methods described herein may improve the user experience of remotely controlling a camera in contexts such as videoconferences.

FIG. 2 is a flow diagram of an exemplary computer-implemented method 200 for updating camera displays. The steps shown in FIG. 2 may be performed by any suitable computer-executable code and/or computing system, including the system(s) illustrated in FIG. 10. In one example, each of the steps shown in FIG. 2 may represent an algorithm whose structure includes and/or is represented by multiple sub-steps, examples of which will be provided in greater detail below.

As illustrated in FIG. 2, at step 210, one or more of the systems described herein may receive, by a camera system that may include at least one camera, input from a user instructing the camera system to adjust a camera frame of the camera.

In some examples, the term “camera system,” as used herein, may refer to a combination of hardware and/or software components that includes and/or directs a camera. In some embodiments, a camera system may control camera settings such as field of view, camera framing, and/or focus. In one embodiment, a camera system may include one or more visual displays that display information from the camera to one or more users. For example, a camera system may display information on the screen of a stationary computing device, the screen of a mobile computing device, a projector screen, and/or an augmented reality headset. In some embodiments, a camera system may include and/or communicate with one or more applications, including but not limited to a videoconferencing application, a video recording application, a social media application, and/or an augmented reality application. In some embodiments, a camera system may be distributed across multiple computing devices. For example, a camera system may enable a user of one computing device to control a camera associated with a second computing device.

In some examples, the term “camera,” as used herein, may refer to a hardware component of a camera system that captures visual information. In some embodiments, a camera may capture still images. Additionally or alternatively, a camera may capture video. In some examples, a camera may have a field of view that encompasses everything visible to the camera. In one example, a camera (or a subsystem that processes input from the camera) may define a camera frame that encompasses everything currently being captured by the physical camera. In another example, the camera system may define a camera frame that encompasses a subset of the area captured by the camera hardware that is processed and/or saved by a camera application. Additionally or alternatively, a camera system may define a frame as the subset of the area captured by the camera that is displayed on a viewing screen. In some embodiments, a camera and/or camera system may have multiple camera frames.

The systems described herein may perform step 210 in a variety of ways. In one example, the systems described herein may receive input via a keyboard, mouse, and/or touch interface of a computing device. In some examples, the systems described herein may receive input via a different computing device than the computing device that is configured with the camera to which the input is directed. For example, the systems described herein may receive the input from the user via a computing device that displays visual data received from the camera to the user and may send, from the computing device, a message to an additional computing device that includes the camera and that is located remotely from the computing device.

In one embodiment, the camera system may include a videoconferencing system and the user may enter input into their own computing device to direct the camera on a computing device that is recording another participant in the videoconference. Additionally or alternatively, the camera system may include a video streaming system.

The input from the user instructing the camera system to adjust the camera framing may take a variety of forms. For example, the user may instruct the camera system to pan the camera frame, tilt the camera frame, and/or zoom the camera frame.

At step 220, one or more of the systems described herein may direct, by the camera system, the camera to adjust the camera framing in accordance with the input from the user.

The systems described herein may perform step 220 in a variety of ways. In one example, the systems described herein may send, from the computing device operated by the user, a message to an additional computing device that includes the camera and that is located remotely from the computing device. In some examples, the systems described herein may direct the camera to adjust the camera framing via a videoconferencing application that is designed to enable users to remotely direct cameras.

At step 230, one or more of the systems described herein may determine a predicted modified camera frame that approximates an actual modified camera frame predicted to result from directing the camera to adjust the camera framing in accordance with the input from the user.

The systems described herein may perform step 230 in a variety of ways. In one example, the systems described herein may determine the predicted modified camera frame by determining the predicted modified camera frame based at least in part on a physical characteristic of the camera. In one embodiment, the physical characteristic of the camera may determine an adjustment rate of the camera. For example, the physical characteristic of the camera may determine the movement latency of the camera (e.g., the lag between when an instruction is sent to the camera and when the camera begins to move), the movement speed of the camera, the acceleration/deceleration of the camera (e.g., the rate at which the camera changes speed). For example, the systems described herein may determine that, based on the motor that rotates the camera, the camera pans at a certain speed and/or pans by a certain amount every time the camera is instructed to pan. In another example, the systems described herein may determine that, based on the components that adjust the lenses to zoom a camera, the camera zooms at a certain speed and/or by a certain amount. In some examples, the systems described herein may then use the information about the movement rate of the camera to determine the delta between the camera frame prior to the movement and the camera frame that will result from the movement. For example, if the systems described herein determine that the camera pans 10° every time an instruction to pan is received, the systems described herein may calculate a predicted modified camera frame that will result if the camera pans 10°. In some embodiments, a camera may provide positional feedback (e.g., the actual angular position of the camera in space) and the systems described herein may use the positional feedback to determine the predicted modified camera frame.

In some embodiments, the camera may be physically integrated into a personal computing device such as a laptop or desktop. In other embodiments, the camera may be a physically separate part of a camera system that is networked to one or more computing devices. For example, FIG. 3 shows a camera 302 that is not physically integrated into a personal computing device. As illustrated in FIG. 3, the systems described herein may determine an adjustment rate of camera 302 based on a physical characteristic of camera 302. In one example, a user may direct the camera system to pan camera 302 from dog 306 to person 304. In this example, the systems described herein may use the physical characteristics of the camera to calculate a predicted modified camera frame that will result from camera 302 physically moving in accordance with the user's input.

In some examples, the systems described herein may determine the predicted modified camera frame based at least in part on the physical characteristic of the camera by dynamically detecting the physical characteristic of the camera. For example, the systems described herein may query the computing device that hosts the camera about the characteristic of the camera. In some embodiments, the systems described herein may query the computing device via the videoconferencing system, which may gather information about camera characteristics of computing systems on which the videoconferencing system is installed. Additionally or alternatively, the systems described herein may monitor the behavior of the camera to determine the physical characteristic of the camera. In some examples the systems described herein may monitor the behavior of the camera during live operation. Additionally or alternatively, the systems described herein may monitor the behavior of the camera during one or more calibration sessions. In one example, the systems described herein may observe that the camera pans 10° every time an instruction to pan is received and may determine that the camera has a physical characteristic that causes the camera to pan at that rate. In some embodiments, the systems described herein may report observed camera behavior and/or characteristics to a repository of camera behavior and/or characteristics to facilitate the retrieval of this information by other camera control systems.

Additionally or alternatively, the systems described herein may determine the predicted modified camera frame based at least in part on the physical characteristic of the camera by identifying the physical characteristic of the camera based at least in part on previously received information about the camera. For example, the systems described herein may receive input from a user that includes the name, manufacturer, and/or type of the camera. In this example, the systems described herein may retrieve information about characteristics of the camera based on the name, manufacturer, and/or type of the camera.

In some examples, the systems described herein may determine the predicted modified camera frame by determining the predicted modified camera frame based at least in part on a latency of a connection between the computing device and the additional computing device. For example, the systems described herein may determine the adjustment rate of the camera via observation but may be hampered by network latency. In one example, if a user presses “pan left” for three seconds, the camera may be warming up and/or accelerating to move for the duration of the first second of input and then may pan left for the remaining two seconds of input. In this example, the systems described herein may calculate the actuation latency for the camera by subtracting the network latency from the time between when the user presses “pan left” and the time when the camera begins to pan left. The systems described herein may calculate connection latency in a variety of ways. For example, the systems described herein may send a ping to the device that is configured with the camera and, time the round trip of the ping, and divide the round-trip time in half to determine the latency of the connection. Additionally or alternatively, the systems described herein may use timestamps and/or synchronized clocks.

Additionally or alternatively, the camera may include a virtual camera and the systems described herein may determine the predicted modified camera frame based on characteristics of the virtual camera. For example, as illustrated in FIG. 4, a tablet 402 may be equipped with a camera 404 that is not capable of physically moving independently of tablet 402. In this example, the camera system may adjust camera 402 by instructing a virtual camera to change which parts of the field of vision of camera 402 are within a virtual camera frame.

Returning to FIG. 2, at step 240, one or more of the systems described herein may display, before completely receiving visual data that results from the actual modified camera frame from the camera, the predicted modified camera frame to the user.

In some examples, term “visual data,” as used herein, may refer to any data that describes a still and/or moving image. In some embodiments, the visual data may include video data. For example, the visual data may be streaming video. Additionally or alternatively, the visual data may include image data. For example, the visual data may be a picture taken by a camera.

The systems described herein may perform step 240 in a variety of ways. In some examples, the systems described herein may display the predicted modified camera frame to the user by displaying visual data received from the camera that is within a field of view of the camera but that is not within a previous camera frame displayed to the user. In some examples, the systems described herein may generate and display predicted visual data. Additionally or alternatively, the systems described herein may display data that is within the previous camera frame and within the predicted modified camera frame.

In some embodiments, the camera may have a field of view that is larger than the camera frame that is displayed to the user. For example, FIG. 5 illustrates a field of view 506 of a camera within a camera system. In some examples, the camera system may display camera frame 502 to a user and may not display visual data from outside of camera frame 502. In one example, a user may instruct the camera system to pan the camera frame to the left. In this example, the systems described herein may predict that panning the camera frame will result in predicted modified camera frame 504. In some examples, the systems described herein may be able to immediately display accurate visual data within predicted modified camera frame 504 because the systems described herein may already receive this visual data due to the visual data being within field of view 506.

In some examples, the systems described herein may display visual data that is within both the previous camera frame and the predicted modified camera frame. For example, as illustrated in FIG. 6, a camera may have a camera frame 602 and a user may instruct the camera system to zoom in. In this example, predicted modified camera frame 604 is entirely within camera frame 602 and the systems described herein may display predicted modified camera frame 604 using data previously received and/or currently being received from the camera.

Additionally or alternatively, the systems described herein may display the predicted modified camera frame to the user by generating visual data based at least in part on visual data received from the camera and displaying the generated visual data within an area of the predicted modified camera frame that is outside a field of view of the camera and does not may include data received from the camera. For example, as illustrated in FIG. 7, a user may instruct a camera system to pan camera frame 702 to the left. In some embodiments, the camera system may not receive visual data outside of the camera frame from the camera and therefore may not have access to visual data for the entirety of predicted modified camera frame 704 until after receiving new visual data that includes the actual modified camera frame. In one embodiment, the camera system may use the visual data within camera frame 702 to create generated data 706 that includes predicted elements based on the elements within camera frame 702. Additionally or alternatively, the camera system may create generated data 706 based at least in part on previously received data. For example, if a user pans a camera to the left and then later pans the camera to the right, the systems described herein may use stored data from the camera's previous position to create generated data 706. In some embodiments, the systems described herein may display the most recent imagery observed at the specified position. Additionally or alternatively, the systems described herein may display an average of a predetermined number of the most recent frames observed (e.g., the most recent ten frames, twenty frames, or thirty frames), use an algorithm to predict, based on a combination of what we previously observed when the camera was at the specified position and is currently visible to the camera, probably visual data within the predicted modified camera frame, and/or display filler data such as color gradients based on previous visual data from the area within the predicted modified camera frame. In some examples, the systems described herein may represent the predicted imagery differently (e.g., grayscale, blurred, and/or dimmed) to distinguish the predicted visual data from actual visual data.

In some embodiments, the camera system may generate filler data to display in areas of the predicted modified camera frame that are outside the previous camera frame. For example, as illustrated in FIG. 8, a user may instruct a camera system to pan a camera frame 802 to the left. In this example, the systems described herein may not have information about what is outside the camera frame and may generate filler data such as generated pattern 806 to display in predicted modified camera frame 804 until receiving updated visual data. In some embodiments, generated pattern 806 may be generated based in part on visual data within camera frame 802. For example, generated pattern 806 may use colors that are common within the visual data within camera frame 802. In other embodiments, generated pattern 806 may be arbitrary and/or may be a preset pattern that does not vary based on received visual data.

Returning to FIG. 2, at step 250, one or more of the systems described herein may receive the visual data including the actual modified camera frame from the camera after the camera adjusts the camera frame in accordance with the input from the user.

The systems described herein may perform step 250 in a variety of ways and/or contexts. In one embodiment, the systems described herein may receive the updated visual data via a videoconferencing application. Additionally or alternatively, the systems described herein may receive the updated visual data via a camera application.

At step 260, one or more of the systems described herein may display the actual modified camera frame to the user.

The systems described herein may perform step 260 in a variety of ways. In one example, the systems described herein may immediately display the actual modified camera frame regardless of the accuracy of the predicted modified camera frame.

In other examples, the systems described herein may smoothly transition between the predicted modified camera frame and the actual modified camera frame by inserting one or more transitional camera frames. For example, as illustrated in FIG. 9, the systems described herein may calculate a predicted modified camera frame 904 after receiving instructions from a user to adjust the camera frame. In one example, an actual modified camera frame 902 may be visibly different from predicted modified camera frame 904. For example, the prediction model used to calculate predicted modified camera frame 902 may be inaccurate (e.g., due to insufficient data about the camera). In some embodiments, upon receiving the visual data that describes actual modified camera frame 902, the systems described herein may calculate one or more transitional camera frames, such as transitional camera frame 906, that are between predicted modified camera frame 904 and actual modified camera frame 902. In some examples, the systems described herein may briefly display transitional camera frame 906 before displaying actual modified camera frame 902 in order to prevent the display from appearing jittery or uneven.

In some embodiments, the systems described herein may be represented by a set of modules stored in memory on one or more computing devices. For example, a computing device 1002 may be configured with a camera system 1014 and may communicate with a computing device 1022 that is equipped with a camera 1018. Computing device 1002 may communicate with computing device 1022 in a variety of ways. In one embodiment, computing device 1002 may communicate with computing device 1022 via a local area network. Additionally or alternatively, computing device 1002 may communicate with computing device 1022 via the Internet.

In one embodiment, computing device 1002 may be configured various modules that perform various functions, such as input receiving module 1004, direction module 1006, determination module 1008, display module 1010, and/or data receiving module 1012. In some examples, input receiving module 1004 may receive, by camera system 1014, input 1016 from a user instructing camera system 1014 to adjust the camera frame of the camera 1018. Next, direction module 1006 may direct camera 1016 to adjust the camera frame in accordance with the input 1016. Before, afterwards, or at the same time, determination module 1008 may determine a predicted modified camera frame 1020 that approximates an actual modified camera frame 1024 predicted to result from directing camera 1018 to adjust the camera frame in accordance with the input 1016. Next, display module 1010 may display, before completely receiving visual data that results from the actual modified camera frame 1024 from camera 1018, predicted modified camera frame 1020 to the user. Shortly thereafter (e.g., within milliseconds, seconds, or minutes), data receiving module 1004 may receive the visual data that includes actual modified camera frame 1024 from camera 1018 after camera 1018 adjusts the camera frame in accordance with input 1016. Finally, display module 1010 may display actual modified camera frame 1024 to the user.

As explained in more detail above, in some embodiments, the systems described herein may provide a user with immediate visual feedback despite multiple sources of delay in receiving an actual updated image from the camera. FIG. 11 is an example graph of the times at which various actions may happen within a camera system that is responding to user input. At time 1101, a camera system may receive input from a user instructing the camera to pan left. At time 1102, the systems described herein may display a predicted camera frame based on the user's input. Meanwhile, at time 1103, the camera may finish accelerating and begin to move at full speed to fulfill the user's request. At time 1104, the camera may finish decelerating and the actual camera frame may reach the position specified by the user input. Between time 1102 and time 1104, the systems described herein may display the predicted camera frame to the user, providing the user with immediate visual feedback despite the actual camera frame not yet having been updated.

As explained above in connection with method 200, the systems and methods described herein may provide users with immediate feedback when users instruct camera systems to adjust camera framing. Users sometimes pan, tilt, or zoom cameras remotely during videoconferences. Unfortunately, there may be significant delay between a user sending the command to modify the camera view and the updated camera view being displayed to the user, due to mechanical delays in the camera response time and/or due to network latency that delays the receipt of commands by the camera and the receipt of the updated camera view by the user. By predicting the modified camera view and updating the camera view displayed to the user to the modified camera view as soon as the user sends input to move the camera, an enhanced videoconferencing system may improve a user's ability to achieve their desired camera view and thus improve the user's overall videoconferencing experience.

As detailed above, the computing devices and systems described and/or illustrated herein broadly represent any type or form of computing device or system capable of executing computer-readable instructions, such as those contained within the modules described herein. In their most basic configuration, these computing device(s) may each include at least one memory device and at least one physical processor.

In some examples, In some embodiments, the term “memory device” may refer to any type or form of volatile or non-volatile storage device or medium capable of storing data and/or computer-readable instructions. In one example, a memory device may store, load, and/or maintain one or more of the modules described herein. Examples of memory devices include, without limitation, Random Access Memory (RAM), Read Only Memory (ROM), flash memory, Hard Disk Drives (HDDs), Solid-State Drives (SSDs), optical disk drives, caches, variations or combinations of one or more of the same, or any other suitable storage memory.
